YouTube Data API - Resumable Uploads - Start a resumable session - Errors

Question

Running into parseError attempting to follow the "start a resumable session" YouTube Data API - Resumable Uploads documentation.

complete list of efforts ,response and code

1. I read on the Google APIs - "Global domain errors" page "parseError The API server cannot parse the request body."
2. I have watched "YouTube Developers Live: Debugging & Dealing with Errors" still know clue there
3. I have read "stack over flow" for similar questions, but never get answered,or answers are still un clear
4. the test youtube account i want to upload to has a youtube channel with videos
5. I tried the client PHP upload API, but found out later its not a resumable upload.
6. I thought resumable upoad would be a better option, so i dont frustrate users, by wasting there time,if there connection drops out....
7. I am runing PHP from hostgator account
8. I noticed how when i did not get an error, it would return the regular snippet and status data and not the "Step 2 - Save the resumable session URI" data
9. I am using long lived access tokens pulled from my database...in the requests, the youtube user has a channel with videos before i stored the access tokens
10. I do check the access tokens with tokeninfo?
11. I noticed changing "uploadType" to "uploadtype" would produce "message": "Media type 'application/json; charset=utf-8'

is not supported. Valid media types: [video/*, application/octet-stream]",following this error by changing content type to "application/octet-stream" would return "kind = youtube#video
object with json snippet,status" not the Step 2 - Save the resumable session URI, so i changed things back to "uploadType" and "application/json; charset=utf-8" now facing same parse error

12. I notice in the docs "Parameter values in the request URL must be URL-encoded." when i would urlencode() "Parameter values" it would return errors or parseError when i removed the urlencode function
13. Even changing "Host: www.googleapis.com" to "Host: https://www.googleapis.com" would produce "The requested URL /upload/youtube/v3/videos was not found on this server. That’s all we know."
14. parse error appears to be most persistent so far
15. I have changed urlencode() to rawurlencode() still parse error
16. i would add charset=utf-8;multipart/form-data;application/octet-stream to content type header, still parse error
17. I notice content type on string is text/plain; charset=us-ascii not sure if google server expects pure application/json

any help would be great…

Answer 1

Easy answer is - you do it wrong.

You are NOT supposed to add "POST", "Host:" and "Content-Length:" into $headers because that is generated by curl (CURLOPT_URL and CURLOPT_POSTFIELDS).

YouTube API works correctly. It is not their fault.
